I'm using a Retrode running v0.19, HW ver 2.2, plugged directly into a USB 3.0 port, the N64 plugin from DragonBox, clean cartridges, and the voltage is set to 3.3V. I'm running Win10, and am using PowerShell's Get-FileHash cmdlet as my verifier.

However, none of my hashes match No-Intro. A few examples (these are my hashes, not No-Intro's):

Have you tried dumping games from systems other than the N64? If you get a Genesis or SNES dump that matches the No-Intro database, then everything is probably working fine, and the N64 plugin is doing something slightly different than whatever dumper No-Intro used to compile its database. If you can dump carts from multiple systems and none of them match the No-Intro database, then you might have a problem, because my Retrode Genesis dumps match No-Intro's.

There is also the issue of byte-order with N64 ROMs.From what I understand, people have been arguing for a long time over what the correct byte order is in N64 ROMs.

(like if you open an N64 ROM in a hex editor, there should be at least a game title in ASCII. IIRC, No-Intro uses the byte-order that creates a jumbled title (like instead of SUPER MARIO 64, USEP RAMIR O46, or whatever)

I just load the DAT files from DAT-o-MATIC into a swiss army knife for ROMs named ucon64 and run ucon64 -rdat *.n64 to rename them. Anything left un-renamed didn't match. (Or without the -rdat to get details)

Before I discovered ucon64, I used a little tool named Snarfblam ROM Hasher (which runs perfectly well in Wine on non-Windows systems) which gives MD5, SHA-1, and CRC32 for the file, the ROM, and the ROM after byte-swapping it.

Emulators don't care, so I've never needed to byte-swap my ROMs, but ucon64 can byte- or word-swap N64 ROMs too.
